Anyone powered up Ho-oh? How about 100% one?

I powered up my Ho-Oh with E/Solar Beam after its initial run to use against Groudon. Probably not much reason to power up one now though.

I haven't powered up one yet, (I'm currently working on a Lugia). But, after my Lugia I am either going for Mewtwo, Ho-oh, or Zapdos to level 30. Eventually though, I will indeed power up a Ho-oh. Mine is weather boosted ES/BB.

I have not. For what it's worth I haven't powered up an entei or moltres either as I don't really see them as having a particularly useful role in the current meta and to the extent they have a role, there isn't that steep of a drop off with subbing in falreon or Charizard considering the differences in resource requirements.

Just because it looks cool, has a nice stat distribution & one of the strongest moves in Solar Beam. Haven't used him an awful lot but I want at least one of each legendary up there. If collecting RC's a problem for you then do the more useful ones first

I powered 1 up as I didn't have access to lugia, and I wanted a tank for Machamp solos, other than that I can't see any use for it

I maxed out a Ho-oh to use for beating down blisseys. It puts out enough damage to get the job done, and isn't as fragile as machamp.
