昔は昔、今は今 Trophy in Super Robot Taisen (PS3 & Vita)

[That was Then, This is Now]
[Use "Convince" on Pikudoron or Girugirugan]

Missable!

Use the ?? [Convince] command on ????? [Pikudoron] or ?????? [Girugirugan] and the trophy should unlock. Both are the ending bosses of the game and they cannot be convinced to recruit. This trophy is just to try to persuade them (unsuccessfully).

????? [Pikudoron] appears as stage boss at Campaign 1 - Stage 10 and at Campaign 2 - Stage 8, whilst ?????? [Girugirugan] appears as stage boss (in different forms) at Campaign 1 - Stage 11,12 and 13 and at Campaign 2 - Stages 9, 10 and 11.
