Big the Cat

Big the Cat (ビッグ・ザ・キャット) is a character from the Sonic the Hedgehog and Sonic Universe series.

Pre-Worlds Collide
Big the Cat was a member of Team Freedom, and was present with them in New Mobotropolis when the Tails Doll attacked. Before anything further happened, the Genesis Wave hit. (Sonic the Hedgehog #247/FCBD 2013)

Worlds Collide
Though Big the Cat didn't play a major part. he had three cameo appearances in the storyline:
 * The first is in Sonic Universe #53 along with Cream the Rabbit and her Chao Cheese when Dr. Eggman is imagining returning to his home reality with the Wily Egg.
 * The second is in Mega Man #27 when Duo is smashing through the Wily Egg, where he is playing cards with Quint.
 * His final appearance (as himself) is in Sonic the Hedgehog #251's Off Panel section, where he gives his condolences to Jet the Hawk regarding not appearing in the Worlds Collide crossover, as his pet frog, Froggy, missed the crossover as well.

Big was also transformed into the Roboticized Master Big Man in the Short Circuits section of Mega Man #27 (making him the unofficial EWN-010), where he proceeded to catch robot fish, to Eggman and Wily's dismay.

Aftermath
Due to Eggman's interference in Sonic's attempt to restore their world, one of the changes involved Team Freedom not existing. Instead of being present in New Mobotropolis to help deal with the Tails Doll, Big & Froggy were instead busy fishing in the w:c:archiesonic:Mystic Ruins Jungle. (Sonic the Hedgehog #253)
