BoBoiBoy Rumble

BoBoiBoy Rumble also known as BoBoiBoy Gentar is an elemental fusion between BoBoiBoy Thunderstorm and Quake. He debuted in the 15th issue of BoBoiBoy Galaxy (Season 2).

Ready to Rumble
Gopal insisted BoBoiBoy to use another fusion because the only fusion he use frequently is FrostFire. BoBoiBoy agreed and in the emergency mission they were given by Koko Ci, he fused Thunderstorm and Quake to form Rumble. Rumble tried to fight the intruder but soon realises that he has no power. The comic ends when Gopal and Qually ran while dragging Gentar when they realized that he is powerless.

Personality
Being the fusion of two serious and responsible elements, BoBoiBoy Rumble is extremely confident in battles.

Trivia

 * In Malay, his name is a portmanteau of Gempa and Halilintar (Malay names of Quake and Thunderstorm respectively).
 * Gopal also nicknames him 'BoBoiBoy Fumble' (BoBoiBoy Hampa in Malay), another portmanteau of Halilintar and Gempa (Malay names of Thunderstorm and Quake respectively).
 * He is BoBoiBoy's most confident form.
 * Gentar means Fear or Frightened in Malay, which is the opposite of Rumble's personality.
 * Though, it can come from the Malay word "gentaran" which means "tremor" or "vibration".
