It was easy! Plus my team was under-leveled. Sure I used a few Revives, but it was like 1 if I remember. And about 2 Full Restores. I didn't lose a single battle during the entire story this was no exception. Maybe it's because I am Ghetsis! His Hydreigon was one of the easier ones for me. I guess I was just lucky.
On White, my first time playing, he was a huge pain to beat. Damn you Hydregion for killing everything I threw at you. D:
On Black, he was beyond pathetically easy it was a joke. Bulk Up Spam Scrafty with Drain Punch and Crunch beat EVERYTHING. Seriously, all I did I was spam Bulk Up 6 times (using Full Restores once or twice while I set up) then sweep. Although, I have to thank Hydregion's Focus Blast missing. If it hit I was pretty much guaranteed to die. xD
Barely managed to beat him on my first try (White version). Used a few revives cause his Hydreigon kept taking put my pokemon in one or two hits. Literally NONE of its moves missed at all. Finally I revived my Zekrom, healed it, it took a hit and ALMOST fainted. I was able to use Fusion Bolt to take him out.
LOL, at first I thought that I had to fight him without my pokemon being healed from N. I was like "WOW. Gamefreak is really pushing us this time".
Yeah. He was closer than most of the storyline battles, but still completely beatable in one go. Honestly, I didn't even have problems with the Hydregion that everybody loves to complain about. One or two Signal Beams and he went straight down. Overall I might have had to use a hyper potion or two - as long as you play type advantage properly, the in-game AI isn't much of a roadblock.
I wanted more of a challenge from both him and N. I was disappointed. :c I was also disappointed they both forced my Zekrom into the beginning of the battle and I had to put in the effort to not kill anything with him before he got knocked out so he would not get evs. :c
I was very scared, however he actually wasnt that hard, even though none of my pokemon matched his levels. He took out a couple of mine, and that Buffallo thing was quite hard to beat. However the rest of them werent too bad, no harder then a Gym Leader.
'Cause I'm just that cool, my Pokemon were all level 53 by the time I got to him. I lost a couple (most notably my newly-captured Reshiram) but otherwise, I blew through it easily.
A couple hundred hours of gameplay later...
My nine year-old sister got to him. I spent hours guiding her level 47s through every step. We had to stall his Hydreigon to actually run out of PP before we won. Otherwise, it OHKOed everybody on her team. Luckily, she was full on Revives from a day of Entralinking.
Hoo, boy. And this is why we grind, people, grind.:naughty:
My initial thought before the battle was: This is gonna suck
My thought after the battle: ...
Yeah, he was pretty easy for me. Used a few hyper potions but that's all really. His Bisharp, Boufallant, and Cofagrigus went down like a stack of cards. His Seismitoad was slugged by my own Seismitoad. Hydreigon was low sweeped by Emboar. Eelektross was a bit tough but Chandelure did the job.
My Pokémon were at level 45-50 (or 48 if one excludes Reshiram) at the time.
