Mega Man X4/Walkthrough

Playing using X

Starting from Magma Dragoon's stage can be advantageous because it's the only Maverick whose boss area X can access with a Ride Armor.

Maverick	Items	Re-visit
Magma Dragoon	Heart	Armor Upgrade (need Arm Upgrade & S. Lion's weapon)
Frost Walrus	Heart, W-tank, EX-Tank (need M. Dragon's weapon)	-
Jet Stingray	Heart, Sub-Tank	-
Slash BeastLeo	Heart	-
Web Spider	Heart, Leg Upgrade (need M. Dragon's weapon)	-
Split Mushroom	Heart	-
Cyber Peacock	Heart, Sub-Tank, Head Upgrade	-
Storm Owl	Heart, 2 Arm Upgrades (need W. Spider's weap.)	-

Playing using Zero

Two of Zero's "weapons" actually are skills that deal no damage, therefore the Maverick order has to be different.

The regular Z-saber deals slightly more damage to Web Spider than to most other Mavericks, while Slash BeastLeo is probably the hardest boss.

Maverick	Weakness	Items & Stage requirements
Web Spider	S. Lion's weapon	Heart (need M. Dragon's weapon)
Split Mushroom	W. Spider's weapon	Heart
Magma Dragoon	W. Spider's weapon	Heart, Ride Armor
Frost Walrus	S. Mushroom's weapon	Heart, W-tank, EX-Tank (need M. Dragon's weapon)
Jet Stingray	F. Walrus' weapon	Heart, Sub-Tank
Cyber Peacock	M. Dragon's weapon	Heart, Sub-Tank (need J. Stingray's skill)
Storm Owl	C. Peacock's weapon	Heart
Slash BeastLeo	W. Spider's weapon	Heart

The table below show the damage inflicted by every Zero's weapon to the Mavericks. Green cells refer to the suggested weapon for each Maverick, red cells refer to weapons obtained from the same Maverick. Split Mushroom's Kuu-en-zan actually deals exactly the same damage as a jumping saber slash, but has better range.

Maverick	Raijin-geki (W. Spider)	Kuu-en-zan (S. Mushroom)	Ryu-en-jin (M. Dragon)	Hyou-retsu-zan (F. Walrus)	Raku-hou-ha (C. Peacock)	Shippuu-ga (S. Lion)
