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 Quake and Thunderstorm for the creation of Rumble. Rumble attempted to attack the intruder but quickly realizes he is powerless. The comic ends when Gopal and Qually ran while dragging Rumble when they realized that he is powerless.

Superheroes in Distress
On listening Adu Du's story, BoBoiBoy Rumble agreed to help him rescue Probe. BoBoiBoy Rumble tried to recklessly engage in battles, but was forced to escape by Gopal and Qually. After a heated chase, Rumble and the others were cornered.

Appearance
Rumble's hairstyle stands out as distinct from the ordinary; he boasts a unique split-bangs look. His eyes are hazel-gold with red accents. Gentar's outfit starts with a vibrant hoodie, featuring a captivating blend of yellow and red hues adorned with crisp white accents. This hoodie boasts two convenient pockets, beneath the hood, he sports a sleeveless jumpsuit, accentuated by a sleek metal chest plate. A black fingerless glove with eye-catching red linings adorns his hand with a touch of urban flair.

Secured around his waist, he sports a metallic belt. His pants, they boast an appealing combination of black, red, and white hues. Continuing down, a pair of black high boots completes his attire. Lastly, his black hat is marked by an elemental symbol that intriguingly merges the essence of earthquake and thunderstorm, forming an almost vibration icon. There are golden designs on each side of the cap, also looking like vibration. His "dinosaur horns" are coloured red.

Personality
Being the fusion of two serious and responsible elements, BoBoiBoy Rumble is extremely confident in battles to the point of being reckless and impulsive. He shows no sign of defeat and fakes to be all right even when things are not.

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 may also come from the Malay word "gentaran" which means "tremor" or "vibration".
 * The possible reasoning for his powers not being generated in time is because he was a rushed fusion and one that BoBoiBoy reluctantly activates.
 * It was also not BoBoiBoy's decision to create a fusion between Quake and Thunderstorm, resulting to him not thinking of a power to give Rumble.
