I'm putting together a team…
I've seen people calling Spider-Man, Superman and Optimus Prime the best representations of heroism. But what about redemption ?

Starscream probably has one of the best arcs in Legend of the Microns/Armada : Despite his flaws and Megatron's constant abuse, he remains a loyal soldier until he finds out that his leader plots to kill him, thus causing him to defect to the Autobots. Later, he would sacrifice himself to prove to Galvatron that the threat of Unicron was real in order to unite both factions.
Despite his immense hatred for Spider-Man, Venom is still bound to his duties as the Lethal Protector. Eddie's even on good terms with Peter.
Vegeta's arc was slow, but beautiful. He comes to Earth and Namek in order to attain immortality, he joins the Z-Fighters in the fight against Cell and renounces fighting after Kakarot's death. During the Buu Saga, he becomes Majin Vegeta in order to become evil again in hopes of beating Kakarot in a 1V1, ignoring Bulma and Trunks' safety. He then proceeds to sacrifice himself to destroy Majin Buu, and puts aside his pride in order to fuse with Kakarot in order to beat Buu, then admits that Goku is his superior during the fight with Kid Buu.
I guess you could add in Burai/DragonRanger as a 4th member, considering he was willingly evil and redeemed himself after he realized his brother still cared for him. As the candle representing the time he has left to live burns out, he wishes Geki to give the elixir of life to a dying child, resulting in his death.
Keep in mind that there's a lot of characters who've redeemed themselves, but in my eyes, these 4 are my favourites.
