Sakuyamon of Digimon Tamers is Renamon's mega form, an armored Shaman Digimon armed with the Vajra Khakkhara and able to summon energy kudagitsune to her aid.
Renamon gains this form when Rika biomerges with her in a leap of faith rather than let her partner face the D-Reaper alone. During the finale, Sakuyamon weakens herself by converting her armor into energy supporting Justimon in an attempt to defeat the D-Reaper.
