Sorry...it's at level 100... or by TM68
You could level your low level Regigigas up to level 100 by giving it EXP. SHARE and then beating the Elite Four a gazillion times, or you could cheat and make Regigigas level 100 when you catch it.
Snow point temple
There exists no trick to get a Level 100 Regigigas in Pokemon Diamond, except by manually levelling up the one found in Snowpoint Temple.
only if you have a level 100 regigigas and a level 100 shaymin
i think its like counter or something?
Pokemon movie nr. 11, you can only get the lvl. 100 regigigas as a gift while you watched the movie, in Japan. Such an event was once, not anymore. but if you want, you can get the lvl. 100 regigigas from a friend, if someone has it :-)
you should have.giratina level 100,regigigas level 100,rayquaza level 100,and a kyogre level 100these Pokemon are really good,maby a groudon level 100.
If you receive Regigigas as an event, it'll be level 100. If you obtain the National Dex and bring Regirock, Registeel, and Regice with you to Snowpoint Temple, it'll appear to be level 1.
He does not learn any moves at level 100.
1000/ 10 but would've given you more if you had an entei. Gameguy100: I can take out your Dialga Arceus and Regigigas with my level 100 Machamp.
