Though it is in no way weak.. I feel like Kingdra deserves a bit of a stat rework/boost. It's bizarre how its Atk, Def, Sp.Atk and Sp.Def are all the same (95), maybe warrants a reduction to Atk and two slight improvements to Sp.Atk and Spd, seeing as it gains no Spd nor Sp.Atk when evolving from Seadra. I also wouldn't particularly mind a boost to both defenses, its dex entries regularly state how it is able to survive and reside within otherwise uninhabitable conditions. Finally, its hidden ability, Damp, would ideally be swapped for something a bit more useful. Sheer Force comes to mind; demonstrates the power Kingdra supposedly possesses and it has a few viable moves to use it with.
All in all, as perhaps the most forgotten Dragon type, I feel a rework to Kingdra could put it back alongside the power of other Dragons. (Sniper/Crit hax aside.)
So my suggested stat spread would look something like..
HP: 75 (same)
ATK: 70 (-25)
DEF: 110 (+15)
SP.ATK: 105 (+10)
SP.DEF: 110 (+15)
SPD: 105 (+20)
BST: 575
So still below Pseudo levels, but with a bit more specialised and usable stats, especially with Sheer Force as hidden ability. And honestly, looking at the HP, I wouldn't be entirely against more Spd and Sp.Atk to make it more so a semi-glass cannon.
