The first time I saw it, I caught it. After that I just made it faint. I didn't even know that it could heal your Pokemon. If that were the case, I'd just torture it until it healed my Pokemon, then I'd defeat it. XD
Currently playing my friend's White file and my Audino guilt got the better of me. I ran into shaking grass without even realizing it and encountered one, so I sent out a Chandelure and used Flame Burst on it, putting it at critical HP and what does it do? It uses Entrainment to give the Healer ability to my Pokemon like it wants to help my team. Guilt got the better of me and I ran from the battle. You have been spared a horrible fate Audino (though I'm pretty sure that Chandelure I had would liked a free soul).
I fought a Lv.52 Audino in Giant Chasm - I sent out my Lv.1 Larvesta, (holding Lucky Egg), switched in my Mienshao and destroyed the Audino before it even had time to Heal Pulse me. I almost felt bad, until my Larvesta got over 13000 XP from the fight and hit Lv.22 in one go.
I feel nothing when Audino gets KO'ed. All it ever does to me is double slap or secret power. Never once has it healed me yet, so I don't care. Even if it did, it's still like battling another pokémon to me, EXP gain is all the same. *shrug*
Okay, i've battled maybe three in White and like none in Black. In White, I caught the first one (Freaking Male at level 17), killed the next one (I think) and caught the level 50 or so one that knew Heal Pulse (also freaking Male).
So no, not really. That picture in the spoiler did make me feel bad though I blame Forever for posting it ;P
I like Audino, back before my data got deleted from me making it halfway through White, it was my primary Pokemon of use in battle. It would literally take out ANYTHING it came in contact with. Now, ever since my first encounter with one and it landed a critical hit on my precious Blitzle and insta-KOed it with a double-slap, I take no remorse in ending its miserable life. The XP isn't bad either XP
