You can't lose to him in the Terapagos battle either, and in the final Terapagos battle the turtle only focuses its attacks on his mons if you're on your last one, and once he's out of mons, it stops attacking altogether. If you still lose, you just warp back in time as usual.
I find it funny the game goes great lengths to make sure you catch the turtle and don't die to it no matter what.
