Notes:

Dear lord, if ever there were a voice I could fu--… nevermind.

Anyways, since The Kid doesn't talk in Bastion, and all of his actions 'n thoughts as well as the story are narrated by Rucks, he would narrate The Kid's actions and performance (and the battle as a whole) in Smash. He would say things for him dealing/receiving heavy hits, edge guarding, taunting, KOs/Falls/Suicides, occasional description of The Kid switching weapons (every time would be overkill), stock/score advantages/disadvantages, etc. Lots of witty stuff, too, with jokes about "no items, Fox only, FD", any combatant using certain items, whenever a player is eliminated, The Kid getting rekt or rekking others, "Kid just rages for a while" if The Kid spams an attack, etc.

Rucks was one of the earlier DLC Announcer/Mega Kill Packs for Dota 2 and he is fantastic. With a visual overhaul for the game included I could see him being a DLC Announcer for Smash, too.
