Martyrous

definitely the knife ears

force powers and high midochlorine count with an un-aligned holocron containing the memory of a master of all force powers and disciplines would be my choice. With a combination of force healing, sith fleshcrafting, and sith alchemy, you could eventually achieve immortality and make yourself nearly unkillable. with the addition of mecha-duru and force stealth, you could become the greatest thief or assassin in existence and mastering the lightsaber forms and defensive and offensive force disciplines and powers could turn you into the greatest space battle mage and warrior in existence. Combine all of the above, and you become a force God. The path would be long, hard, and likely nearly impossible, but not completely unachievable.

I would argue that force breathing falls under the combined tree of the knight speed and battle meditation force powers. Knight speed provides a boost in physical abilities, while battle meditation provides heightened battle awareness and cognitive abilities as well as allowing masters of the technique to telepathically guide troops in battle almost like a commander in an RTS game.

To be fair, Emily was the little girl who got shot by Hydra at the orphanage, and with how similar the author made, the character names, I can see how they might get confused.

some of the greatest sith lords in OG Star Wars lore weren't just masters of death, rage, and fear, but creation and life as well. You should check the lore of sith alchemists and fleshcrafters those guys were hard-core and could be considered nearly impossible to kill at the heights of their power. Plus, fleshcrfting is probably the best discipline to master if you want superhuman strength, agility, endurance, and durability, as well as one of the few paths to immortality that doesn't require you consume the life-force of entire worlds or to commit untold horrors against the Innocent.

killing them without a means of destroying the evidence of your involvement? Yes, very dumb. However, if you did have a way of destroying the evidence, removing these scum from the equation does solve a lot of problems. Habitual criminal offenders do not learn from their mistakes they don't become law-abiding citizens after being released from prison. No, the truth is in their titles as "Habitual Criminal Offenders." and the criminal punishment system does very little to prevent them from re-offending. Many may think it harsh, but at some point, you need to stop giving people a chance to change for the better and cut the cord in a more permanent fashion.

considering that Tyr will probably have to learn through self-study since there's no Jedi or Sith Order's in the Marvel, he will probably learn some obscure techniques via experimentation. Force stealth, for example, is extremely rare and underutilized in Star Wars cannon lore.

A joke in good humor and not just to mock a being beyond mortal comprehension? A decent non-evil God and even some of the more lawful evil sorts would probably take it in good humor as long as you aren't being rude or disrespectful towards them. However, if you are dumb enough to start cracking jokes about them and being disrespectful in their presence, congratulations on winning your own personal Darwin Award!!

courtesy can go a long way when meeting someone for the first time regardless of their rank, social class, or wealth. Respect, however, is something that must be earned, not given, and let's be honest regardless of the Isekai and reincarnation tropes common in webnovels, anime, and manga, wouldn't you be skeptical if a God showed up out of the blue and offered you a path to untold power with seemingly no strings attached? That just screams it's a trap, and "I'm going to enslave your soul to my will for all eternity" to me.
