In crossovers with other shonen series, characters like Luffy from One Piece can be paired with Ichigo. Their different personalities and power sets would create interesting dynamics.

Luffy from One Piece is also a common pairing. Luffy's carefree and adventurous nature combined with Ichigo's more serious and duty - bound personality would lead to some really fun and unpredictable interactions. They could be on a quest in a crossover world, with Luffy's devil fruit powers and Ichigo's Soul Reaper abilities working together in strange and amazing ways.
Characters like Naruto from the Naruto series could be an interesting pairing. Naruto's positive attitude and his own powerful jutsu could be a contrast to Berserker's darker nature. Also, Captain America from the Marvel Universe would be a good match. Cap's leadership and moral compass against Berserker's more chaotic nature would create an interesting conflict. And for a more fantasy - based pairing, Legolas from The Lord of the Rings. His archery skills and elven grace against Berserker's brute strength would be a great visual and story - wise combination.
Gintoki from 'Gintama' could be paired with Shizuo. Gintoki's laid - back yet strong - willed personality next to Shizuo's short - tempered and powerful nature would result in some hilarious and action - filled interactions.

The cool and collected Spike next to the hot - headed Shizuo would make for an interesting character study and some great action sequences.
Dante from Devil May Cry would be an excellent character to pair with Doomguy. Dante is a stylish demon hunter, and when combined with Doomguy's brute force approach, it would create some really cool action scenes. Also, Samus Aran from Metroid could be a good match.

In crossover fanfiction, Luke Skywalker would be an excellent character to pair with Darth Revan. Luke's journey from a farm boy to a Jedi Master could contrast with Revan's fall and redemption.

Also, Shepard from Mass Effect could be a great pairing. Their different approaches to leadership and combat would create an engaging story.

One interesting character to crossover with Ichigo is Light Yagami from Death Note.

Saitama from One - Punch Man could also be a great choice. Saitama's overpowered nature and Ichigo's journey to become stronger would make for an interesting story. And what about Alucard from Hellsing? His vampire powers and Ichigo's powers related to the afterlife would create a really dark and exciting crossover.
Jack O'Neill from Stargate could be an interesting character to pair with Duncan MacLeod from Highlander.
