Brief quibble: Black Mage has used more then 4 Hadokens. Off the top of my head:-
*Killing the first giant they met
*To cushion a deathtrap crash
*to blow up the volcano Fighter and Red Mage were standing on
*Blowing up an iceberg whilst on the boat crewed by the dark warriors
*Destroying the boat full of supplies for the orphanage
*The attempt to kill Red Mage just as they got their class changes
*The example at the top of the page.

Could we rename this trope "KamehaDoken"? No real reason other then the fact it is shorter.
**Well, [[BigYes yes]], [[{{Wii}} we]] ''could'', [[BabyGotBack but]] with the current version, [[{{Wii}} we]]'ve got the full names [[FantasticFour for]] both attacks, and renaming it "Kameha Doken" would leave the name incomplete for the "Ka[[{{Pokemon}} me]]hameha" part. So, probably [[BigNo no]]t.

*Lucario's energy ball attack is named hadou''den'' in Japanese.
