Mega Houndoom
I just realised that there is no Mega-Houndoom move set on here, so I figured I should change that.
Houndoom @ Houndoominite
Ability: Flash Fire
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Nasty Plot
- Fire Blast
- Dark Pulse
- Solar Beam
This should be used on a sun team (obviously). Houndoom is only really any good on sun team because of his new ability, Solar Power. Even then, he is usually not considered because of Mega-Charizard Y, who can set up his own sun. However, Houndoom is still very good. With base 140 Special Attack, even before the Solar Power boost, he can wreck havoc on most teams. If he manages to get a Nasty Plot boost as well, then even resisted hits will do considerable damage. Fire Blast is really the move that will destroy everything on this set, with the sun boost, as well as STAB, Solar Power, and Houndoom's base Special Attack, it wrecks everything.
For example: On a damage calculator I got this result:
+2 252 SpA Solar Power Mega Houndoom Fire Blast vs. 252 HP / 0 SpD Tentacruel in Sun: 365-429 (100.2 - 117.8%) -- guaranteed OHKO
So even a Specially bulky Pokemon that resists it is defeated by 1 Fire Blast, after a Nasty Plot.
Also, its base ability, Flash Fire, allows it to switch into a predicted Fire attack to get a boost to Fire Blast. Of course, it loses this after it mega evolves, but it is still nice for the first switch in.
