Character Mastery in Invincible VS is the per-fighter progression track that runs alongside the game's profile masteries. Every playable character on the launch roster has its own mastery ladder that climbs from level 1 up to level 23, and you can browse the full set from the customization menu without ever entering a match.
Quick answer: Each of the 18 launch fighters has a 23-level Character Mastery track, viewable under Extras → Collection → Customization → Character Mastery.

How to open the Character Mastery screen
The mastery menu is buried a few layers into the Extras section rather than living on the character select screen. The path is consistent across platforms.
Step 1: From the main menu, choose Extras. The submenu shows Collection, Replays, and Credits.
Step 2: Open Collection, then select Customization. You'll land on a screen with a top navigation bar containing Profile, Customization, Character Mastery, and Loadout tabs.
Step 3: Switch to the Character Mastery tab. From here, cycle through fighters to see each one's 23-tier reward track.

Launch roster covered by Character Mastery
All 18 base fighters have full mastery tracks at launch. The roster leans heavily on Viltrumites and Guardians of the Globe, with a handful of villains and tech-based characters rounding things out.
| Fighter | Archetype / Role |
|---|---|
| Invincible (Mark Grayson) | Balanced all-rounder with strong aerial pressure |
| Atom Eve | Mid-range control and zoning with hover mobility |
| Omni-Man | Offensive powerhouse, low defense, heavy pressure |
| Battle Beast (Thokk) | Heavy hitter with super armor and big damage |
| Bulletproof | Close-range combo fighter with high/low mixups |
| Rex Splode | Trap and explosive setup specialist |
| Thula | Mid to long-range pressure and rushdown |
| Cecil Stedman | Ranged harassment, gadgets, support calls |
| Robot | Technical ranged pressure from multiple angles |
| Monster Girl | Straightforward brawler with grapples and throws |
| Anissa | Aggressive close-range, long combo strings |
| Lucan | Grappler with crushing pressure and low pokes |
| Powerplex | Electrical space control, ground and air |
| Dupli-Kate | Clone-based combos with extended reach |
| Allen the Alien | Grapples and counters, durable mid-weight |
| Titan | Super armor heavy with rock-based attacks |
| Ella Mental | Elemental ranged fighter with varied projectiles |
| Conquest | Striker with armored charging punch and extreme pressure |
What the 23-level structure looks like
Every fighter shares the same 1-to-23 mastery ceiling at launch. Tiers unlock as you accumulate match experience with that specific character, and progression is tracked independently from your profile-wide masteries. Switching characters means starting a new ladder from level 1 for that fighter.
Because the track is per-character, a player who mains a single fighter will see that one ladder fill out fast while the rest sit untouched. There is no shared XP pool that pushes multiple characters forward at once.

How to confirm your progression registered
After a match, the Character Mastery screen for the fighter you used should reflect new XP toward the next tier. If the bar hasn't moved, the most common reasons are that you played as a different character on your team for the round counted, or that you were in a mode that doesn't award mastery progress (such as pure local Versus on some configurations). Online connectivity also matters for syncing rewards to your profile.

DLC characters and what comes after launch
Two confirmed post-launch fighters, Universa and the Immortal, are slated to arrive in summer 2026. Both will ship with their own Character Mastery tracks once added to the roster. Additional DLC characters beyond those two have not been formally confirmed yet, so any further mastery ladders depend on future season announcements.
Picking a fighter to grind first
If you want to climb a mastery track quickly without fighting your character as much as your opponent, the more straightforward kits are the safer first picks. Invincible and Bulletproof both reward simple fundamentals. Monster Girl's brawler kit and Omni-Man's pure offense also let new players see results without deep execution requirements.
The harder mastery grinds tend to be the technical or setup-heavy fighters: Cecil's gadget play, Dupli-Kate's clone management, Robot's multi-angle pressure, and Conquest's armored timing all demand more practice before wins start coming reliably.
Mastery tracks are cosmetic and progression-focused rather than tied to balance, so picking a main based on playstyle fit will serve you better than chasing a perceived easy ladder. Once you've decided, the Character Mastery tab is where you'll watch the work pay off, one tier at a time.
