Seeing Dr. Wright pop up on the site today kinda sparked the idea. I thought it might be cool to have a Metroid as an assist trophy. He could latch on to other players and slowly increase their percent, after awhile it would return to the owner of the trophy and reduce his percent. The opponent could mash buttons or do something else to decrease the latch on time and shake the metroid off. I think it would be a cool idea and add some nice health strategy other then grabbing a heart or food on the ground.
