Negotiating Character Rules: A Developer’s Guide to Marvel’s ’90s Approval Process (Juggernaut Case Study)

Overview

In the early 1990s, Marvel's partnership with Capcom began with the arcade beat ‘em up The Punisher (1993). The collaboration quickly shifted to fighting games with X-Men: Children of the Atom (1994), leveraging the immense popularity of the X-Men franchise at the time. However, Marvel was notoriously protective of its intellectual property during this era, imposing strict guidelines on how characters could behave, move, and even appear.

This guide examines a famous hurdle in game development: Marvel’s insistence that the Juggernaut—a virtually unstoppable, tank-like villain—could not jump. Former Capcom localization lead Takuya “Tom” Shiraiwa recounted the struggle to Time Extension, revealing how Capcom had to negotiate every animation frame. This case study serves as a practical tutorial for developers, producers, or licensing teams dealing with character restrictions in licensed games.

Prerequisites

Step-by-Step Instructions

Step 1: Build the Initial Character Roster

Before any animations are created, developers must propose a list of playable characters. Marvel’s first gate is character approval—just because Spider-Man appears in X-Men comics doesn’t grant automatic inclusion in an X-Men game. Shiraiwa noted that the first round of conversations was always about which characters would be allowed. For Juggernaut, his inclusion as a major X-Men antagonist made sense, but his movement capabilities remained undefined at this stage.

Step 2: Submit Character Animations on Videotape

After the roster is locked, Capcom would animate each character’s full set of moves (idle, walk, attack, jump, etc.) and record them onto videotape for Marvel’s review. This was standard procedure. For Juggernaut, the submission included a jumping animation. Marvel’s response was clear: “No, Juggernaut can’t jump. He’s too heavy.”

Key documentation to prepare:

Step 3: Reason with the Licensor Using Logical Scenarios

Shiraiwa acted as the middleman. He reasoned with Marvel using a practical question: “What’s he gonna do when he finds a big hole in front of him? Like a big gap? Will he be able to jump then?” Marvel’s surprising answer: “No, in that case, he will simply fall into the hole and just keep running when he lands.”

This response shows that Marvel’s logic was internally consistent—Juggernaut’s unstoppable nature meant he wouldn’t be deterred by a hole. But in a fighting game, that answer was unacceptable. Shiraiwa countered: “This is a head-to-head fighting game; he needs to jump.” He highlighted the core gameplay requirement: vertical space for aerial combos. Without jumping, Juggernaut would be unable to interact with flying characters or navigate platforms, making him unplayable.

Negotiation tactics used:

Step 4: Achieve Approval Through Persistence

Capcom eventually got its way. In X-Men: Children of the Atom and the follow-up Marvel Super Heroes, Juggernaut absolutely jumps. This was crucial because Capcom’s superhero games featured extra-high levels with ample vertical space for aerial combos—a major selling point. The approval likely came after multiple rounds of discussion and perhaps a compromise that Juggernaut’s jump could look weighty (e.g., a heavy landing).

Step 5: Observe the Post-Release Shift in Licensing Attitude

After Capcom released one or two extremely successful Marvel fighting games, Marvel’s stance changed dramatically. As Shiraiwa recalled, “They were like, ‘Anything goes. You can do whatever you want.’” This shift underscores the power of proven success. Modern Marvel, as seen in games like Marvel Rivals, is far less nitpicky about character movements—even allowing Juggernaut to twerk. The lesson: financial success can loosen rigid licensing rules.

Common Mistakes

Assuming the Licensor Will Be Flexible

Many developers expect early cooperation, but Marvel in the ‘90s had strict rules based on perceived character integrity. Do not assume that any animation will be approved without justification.

Failing to Provide Concrete Gameplay Context

Shiraiwa succeeded by asking a specific question about a hole. Vague arguments (“jumping is fun”) are weaker than functional necessities (“the character cannot progress through the level”). Always ground your requests in the game’s mechanics.

Ignoring the Possibility of Alternative Solutions

Marvel offered an alternative (fall into hole and keep running), but it didn’t solve the fighting game problem. Developers should be ready to propose multiple workarounds—but also stand firm on core needs.

Not Documenting the Approval Process

In the ‘90s, videotapes were used; today, modern equivalents (video files, frame-by-frame reviews) should be archived. Without records, future games may face the same hurdles.

Summary

This case study demonstrates how Capcom navigated Marvel’s strict character rules to allow Juggernaut to jump in X-Men: Children of the Atom. Key takeaways include: start with roster approval, submit detailed animations, use logical gameplay scenarios to reason with the licensor, persist through multiple rounds, and leverage success to relax future restrictions. For modern developers, the lesson is that early relationship-building and respectful negotiation can overcome seemingly absurd limitations—and that money, as Shiraiwa noted, changes everything.
