Infinity Jump (also called Continuous Jump) refers to the ability of certain characters in the Kirby series to jump in the air repeatedly. It usually allows for an indefinite number of midair jumps to be performed, hence its name; however, it is limited in Kirby Battle Royale, Kirby Fighters 2, and Kirby and the Forgotten Land. The Infinity Jump technique can be performed by most Helpers in Kirby Super Star and Kirby Super Star Ultra, by most Friends in Kirby Star Allies, and exclusively by Bandana Waddle Dee in Kirby's Return to Dream Land, Kirby and the Rainbow Curse, Kirby Battle Royale, Kirby Fighters 2, and Kirby and the Forgotten Land; it is also usable by Kirby if he is using the Wheelie Rider ability, possessing an appropriate enemy using the Ghost ability, or Piggybacking on a character who can use it. The technique exists so that these characters can keep up with characters who can fly, such as Kirby, King Dedede, and Meta Knight. It is debatable if this technique is canon to the story, or just a gameplay element to make these characters more viable.
The Infinity Jump technique appears in the following Kirby games:
- Kirby Super Star / Kirby Super Star Ultra - performed by most Helpers and Wheelie Rider
- Kirby: Squeak Squad - performed by most enemies while they are possessed by the Ghost ability
- Kirby's Return to Dream Land - performed by Bandana Waddle Dee
- Kirby and the Rainbow Curse - performed by the Waddle Dee partners
- Kirby Battle Royale - performed by Waddle Dee and other minor characters
- Kirby Star Allies - performed by most Friends and some Dream Friends
- Kirby Fighters 2 - performed by Bandana Waddle Dee
- Kirby and the Forgotten Land - performed by Bandana Waddle Dee
Kirby Super Star
Kirby Super Star was the first Kirby game to feature the Infinity Jump, as most Helpers required it in order to be able to keep up with Kirby as he traversed the stages. In this game (as well as Kirby Super Star Ultra), Infinity Jumping in the air is more intensive in terms of vertical gain than Kirby's hover, since the jump offers the same height as each hover flap, but the jumpers are still fully affected by gravity unlike Kirby.
Kirby and the Rainbow Curse
In Kirby and the Rainbow Curse, each of the Waddle Dee partners gains access to the Infinity Jump for the purposes of keeping up with Kirby and Elline's rainbow ropes. However, the mechanics of jumping in this game are different to those of the main series. For instance, there is a delay between being able to perform jumps, meaning it cannot be rapidly tapped. In addition, jump steering is limited, and each subsequent jump in the air gains less height, making this jump skill not actually infinite at all. Eventually, the Waddle Dees will no longer be able to gain height, and will fall, only able to regain their full jump when touching the ground again.
Kirby Battle Royale
This game marked the first time that Bandana Waddle Dee's Infinity Jump was limited in how high it can go, in a similar way to other forms of flight in that game. It otherwise functions the same way as in the main series.
