No.

Snake Summons.

Swift Release for sure. Speed is absolute. Use the Creator perk to recreate the Chimera technique and then perfect it. Absorb genetic material from the Uchiha, Senju, Uzumaki, the clan whose illusions affect real life and the clan who can control their bones to fight.

LOTR sword is better though.

A bit longer and thinner would be nice.

Toad.

No.

The Black Pearl!!!

He can build The Black Pearl himself just fine. Meet the master shipbuilders and merge their shipbuilding skills together. A galleon made with blackened wood and brass fixings a black flag with threaded gold trim and sigil of House Blackfyre. He can also carve the likeness of the gods into the ships mast or railings to receive their blessing for their domains that are relevant to the ship. Lord of Light makes it fireproof. Drowned God makes it unsinkable. Etc.

Go for it.

Do her anyway.

Goddess of Knowledge and Wisdom. Plus Ultra!!!

I have a suggestion if you like. You can have your intended harem become the Uchiha main branch and have those you're not fond of or don't like but they like the MC can be given the chance to be a part of the newly established side branch of the Uchiha that the MC will create after achieving his goals.

The benefits obtained from leaving the village with Orochimaru far outweigh the risks especially when OG Sasuke was able to beat him with just 3 years of dedicated training while current MC will have many more years of training to build an exceptional foundation for future training especially by Orochimaru. Orochimaru wouldn't try to possess Sasuke until his Sharingan was fully mastered his various jutsus were honed to the extreme and body trained and enhanced to perfection.

MC could take ideas from the shows and movies recreate them in real world and use them for reference in his shows and movies and books including comics.

MC can also pull in ideas from other real-world books, shows and movies. Like The Player tv show, Nikita tv show, Assassins Creed movie, Wanted movie, Infinite movie and Jason Bourne books and movies. Those that don't make the cut for Overwatch just barely can be eligible to become The Player... one in each continents' gambling centre Macau, Las Vegas etc. The Player, The Dealer, The Pitboss and The House. You can watch The Player and Nikita on Tubi for reference if you like. As for Nikita and Jason Bourne a joint operations type deal with the government for clandestine activities both domestic and foreign to protect the country. A semi-official project. Government higher ups in the know. Need to know for others. Assassins Creed and Wanted type organization that recruits and trains those who are innately gifted with talent in given craft. Infinite is primarily a secretly owned and operated tech company completely separate from the outside world similar to the movie with all accounts and transactions done clandestinely through Swiss banks boasting the highest security measures. All deeds official and unofficial should be stored in a Swiss vault inside a safety deposit with multiple nonphysical countermeasures save a very unique key that will be hidden in the corner under the basement concrete floor of MC's house like John Wick did. I said nonphysical countermeasures in case you decide to give the MC another ability in which case I think the power of reincarnation from the Infinite would be perfect not weak or overpowered. No fingerprints or retinal scanner because he'd be reborn in a different body. Just a very long pin# a very complicated password maybe a puzzle in the unlikely event that the MC were to die. I'll leave it to you to figure out for yourself. Peace.

You can have him pick up the resurrection stone after Harry drops it in the forest before the final battle. You can also kill off Lucius Malfoy during the actual battle so he doesn't find out MC knocked up his wife sometime before the battle. You can likewise get the twin wands after the final battle and Voldemorts' death. Harry's broken wand and Voldemort death wand or cursed wand whichever it is. Combine the wands and stone to the MC's wand with that wand strengthing ritual that was set up in advance before the battle. As for Beatriax after she escapes Azkaban you can try to seduce her or wait til she dies and have one of the house elves secretly take her so you can revive her after the battle when MC truly becomes Master of Death and gains power over death. If you're worried about being to OP'rd set some restrictions like in Naruto to only be revived within I think an hour of death or if they've been dead longer than the set timeframe you'd have to sacrifice a life or a certain amount of lives to bring them back from the afterlife. Like Lily Potter, Marilyn Monroe, Joan of Arc, Helen of Troy and Morgana Le Fey etc.

Mark should be careful about making bulletproof clothes cheaply and for everybody. The current Underarmor outfits can do that. Although not completely. The bulletproof clothing should be high-end like the movie. And it should require an up-to-date picture ID. To avoid criminals getting them easily. You can also recreate the Continental in this world if you haven't already...I can't remember if you did. Make it globally like the movie with the same or similar rules for those who stay there like assassins, hackers and Overwatch members. Mark will be the hidden shadow owner and represent and lead the high tables' highest levels with other members unaware of his true power and position. He could play as the high tables' treasurer to avoid making a move personally. No organization would risk their moneymaker or bookkeeper unless absolutely necessary. Boom!!!

The Wrap of Quantum Darkness suits him best.

Perfect.
