Tonihiru are thunder element Carapaceon. They are often seen with Venelarius.


Tonihiru Icon by Chaoarren Jungle dwelling Carapaceons with electric pincers powered by conductive spikes on their backs. They have been known to follow Venelarius in search of food, and can even form a sort of, "merge" with it by mounting them.

The shape is like if Daimyo Hermitaur lost its shell and got Ceanataur pincers. The main body has a blue colour which sometimes glows yellow in patches. Covering the legs is green moss, resembling that of the Venelarius. Along the back line several dark blue spikes.


These crabs can use thunder element from their pincers, generated from the spikes on its back. Normally they won't try to fight much unless enraged or there is a Venelarius nearby. Venelarius have a strange bond with these, they have ridges on their backs allowing them to merge with them and aid it, then feed on food remainders left.


  • Sparking Pinch: Jungle (2nd): Area 3

The hunter walks towards the river bank, seeing a spark come from the foliage. A pincer strikes out from it, following with the crab. It clutches both together twice, charging them as it walks forward towards the hunter, looking to be a reasonable hunt.

Rage and Tired states

  • Enraged: Pincers become electrified and bubbles foam in mouth.
  • Tired: Will fail to use thunder swipes and will drool.


  • Left Pincer Wounded
  • Right Pincer Wounded
  • Left Legs Wounded
  • Right Legs Wounded

  • Swipe: A quick swing from one of its pincers. (Can be done while on Venelarius)
  • Thunder Swipe: Charges up a pincer and swings it in an arc like Shogun/Plum Daimyo. This obviously causes Thunderblight. (Can be done while on Venelarius)
  • Stab: Moves forward and stabs downwards at a target, piercing into the ground for a second. (Can be done while on Venelarius but doesn't pierce to ground)
  • Double Stab: Shakes its pincers and does a stab with both pincers one after the other, taking a step forward with each.
  • Thunder Stab: Lifts a pincer upwards to generate thunder element through it then does its stab, creating a larger range of attack from the sparks. (Can be done while on Venelarius)
  • Double Swipe: Does the swing with both pincers forward.
  • Thunder Spark: Its pincer will spark with thunder. The pincer swipes at the target, launching sparks at the target. (Can be done while on Venelarius)
  • Leap: Bends down and jumps onto a target. This isn't as far as Daimyo's.
  • Merge: Will leap onto Venelarius's tail and is launched onto its back. It will attach onto its back by the ridges with its legs and give Venelarius thunder element to its horn and tail.

(High Rank and above)

  • Leap Slash: Right as it lands it slams its pincers into the ground.

(G Rank only)

  • Thunder Leap Slash: The attack is now electrified unless both pincers are broke.
