Trumpy

Trumpy, known as Rarapappa (ララパッパ) in the Japanese version, is a virus in the MegaMan Battle Network series that resemble a horn wearing headphones. They appear in later MegaMan Battle Network games starting with MegaMan Battle Network 3.

A Trumpy jumps up and down in the right-most column on the enemy's side, pausing after four jumps to play music that will affect either MegaMan or its allies. However, Trumpies don't benefit from their own music.

Trumpy
Trumpy is a yellow variant. They have 90HP in BN3 and BN5, 60HP in BN4, and 80HP in BN6. Their music makes its allies invincible.

Tuby
Tuby is a blue variant. They have 150HP in BN3, 100HP in BN4 and BN6, and 120HP in BN5. Their music confuses MegaMan. Moving up on the D-pad makes you move down, etc.

Tromby
Tromby is a pink variant. They have 200HP in BN3, 140HP in BN4, 150HP in BN5, and 130 in BN6. Their music immobilizes MegaMan.

MuteAnt
MuteAnt is a grey variant. They have 180HP in BN4 and BN5, and 160 in BN6. Their music prevents MegaMan from attacking.

Xylos
Xylos is an orange variant. They have 220HP in BN4 and BN5, and 190HP in BN6. Their music recovers HP to its allies.

TrumpySP
TrumpySP is a green variant. They have 260HP in BN4 and BN5, and 210HP in BN6. Their music makes its allies invincible.

Battle Chips
Trumpies yield Fanfare battle chips when deleted. These chips summons a 100HP Trumpy virus (60HP in BN6) in front of MegaMan that causes different effects while playing. The Trumpy can be destroyed by enemy attacks.

Fanfare
A yellow Trumpy is summoned. When it plays, MegaMan is invincible to attacks. The Trumpy is still vulnerable, though.

Discord
A cyan Trumpy appears and causes enemies to become confused for the duration of its song.

Timpani
A pink Trumpy is summoned, whose song immobilizes enemies while it plays.

Silence
A gray Trumpy appears and prevents enemies from attacking while it plays. This does not affect Elemprors however.

Dark Sonic
Dark Sonic is a Dark Chip only found in Battle Network 5. When used, it summons a purple Trumpy with 100HP whose music paralyzes all enemies. Other than the health penalty caused by using Dark Chips, a bug occurs that causes MegaMan to instantly teleport to the edge of his side of the field.
