So you know how Assist trophies work right? You summon a character that didnt quite make the final cut. However, since the Assist Trophy is an item, most people dont use it. I have a better idea, what if character could summon their own personal assist. Here's how it would work, when you choose a character, you can choose one of three assists from their series, that character would help out and then disappear when they are KOd. Each assist would have low health and only one attack.
Examples:
Mario Series:
-Lakitu: Spiny Throw
-Hammer Bro: Hammer Throw
-Kamek: Magic Blast
Phoenix Wright Series:
Miles Edgeworth: Take That!
Lana Skye: Knife Stab
Steel Samurai: Spear Stab
Mega Man:
Elec Man: Thunder Beam
Fire Man: Fire Storm
Time Man: Stops time for 5 seconds then leaves
