So for anyone curious about the Rage situation in the Android version, Tonberries is still unusable, but they did actually change it a bit. It used to be that the Tonberries appeared on the Veldt, had a Rage programmed in, that Rage could be acquired, but that Rage was unusable because of an oddity in the way the game handled battle commands (specifically, it required at least one empty slot in any battle command menu, the menu could hold 255 commands, and Tonberries was Rage #255, rendering it unselectable). In the Android version Tonberries still appears on the Veldt, but they don't have a Rage. Leaping them gives you nothing. They're sorta like Proto Armor that way, now.
It's a real pain, since the Tonberries Rage is the strongest physical attack Rage in the game, and is basically the direct upgrade to Stray Cat. Of all the bugged Rages it was the most important one by far, and it was also the one I was most hoping was fixed since it was fully functional but was only unusable owing to a quirk of the battle menu system. And instead of fixing it they dummied it out entirely. I Leaped the Tonberries twice to make absolutely sure, and they don't show up in the Abilities menu on the status screen or on the in-battle command list.
I think it's a serious missed opportunity, really. Since Proto Armor and Tonberries aren't fixed I think it's pretty safe to operate under the assumption that Siegfried and Typhon aren't fixed either, and so there's still no version of Final Fantasy 6 that has a full Rage command list (if we're defining "full list" as "all enemies that appear on the Veldt have Rages, and all enemies that have Rages appear on the Veldt," which I think is a rather reasonable definition).
