Several stories and mythological literature illustrate the story of Vidar. Unfortunately, his complete portrait was not mentioned in these works. There is no concrete fact other than his character and indictment in Ragnarok.
About Vidar
Vidar is pronounced “Vih-dar”. This name comes from Old Norse Víðarr, meaning "great ruler" or "great leader". According to mythical legends, Vidar is a god of war and silence. It is the youngest generation of gods who experienced Ragnarok, the destruction of the cosmos.
Vidar was the son of Odin, the brother of Thor, Loki, Heimdall and Baldur. He is considered the strongest god after Thor. In the new world, after Ragnarok, he became the strongest god after Thor's son named Magni, his nephew.
Norse tales and mythical books said that Vidar is one of the Ases gods like the god Vali. However, he plays an important role in Ragnarok. His wisdom and thirst for revenge allowed him to gain the upper hand over the Fenrir. Moreover, this event is even illustrated in stanza 17 of the mythological poem entitled “Grimnismal”.

Many literature references speak of this ase god such as the work of the legendary Edda of Snorri or Snorri Sturluson, in the Gylfaggining, the Skaldskaparmal. The famous writer of the Poetic Edda singles out Vidar, in his mythological poems “Voluspa”, “Lokasenna”… Vidar is also mentioned several times in the work of the great historian Georges Dumézil.
Two places in Norway bear his name: the Virsu or Viðarshof, which means "Vidarr Temple", and the Viskjøl or Viðarsskjalf, which means the "Crag or Pinnacle of Vidar". In this regard, it is likely that Vidar figured in Scandinavian pagan religious practice.
Vidar: Fenrir's Slayer
During Ragnarok, the gods allied with Odin tried to preserve the cosmic order. The majority of them left their skin to defend the universe against the chaos giants: the gods of destruction and havoc, like the goddess Vishnu.
In the heat of the war, Odin was slain by the Fenrir, a large dire wolf. Her son Vidar, whose mother called Gríðr, is a giantess who set out to take revenge for her death. Overwhelmed with anger, he put on the sturdy shoe he fashioned himself. Then he attacked the beast by opening its lower jaw. Then, he held the Fenrir's upper jaw open and used his sword to cut the wolf's mouth into pieces.

Through courage and willpower, Vidar managed to kill the Fenrir.
Vidar: the god of silence
Asgard was a realm full of trees, flowers and bushes. Before the arrival of Ragnarok, this young god spent most of his time in the woods and in his garden. He remained alone in his personal space, flowing in calm and silence. It is perhaps even because of this that he achieved his status as the God of silence.

@ChuckKennedy
Vidar's story centers around revenge for her beloved father. There are no other chapters that speak of its description. All we know is that his particular weapon is silence.
The lesson in all of this is to never underestimate the power of silence. The guaranteed delivery of success is none other than silence. Moreover, it is one of the rare qualities in humans.
The archaeological records illustrating Vidar

@Forged In Wood
According to archaeological records, this silent god may reflect the image of a man tearing through a wolf's jaw on the Gosforth Cross in northern England and Kirk Andreas' Cross in the Isle of Man. These two legends date back to 900 AD and could represent Vidar and Fenrir .
From another point of view, Vidar and the wolf could also represent Christ and a wolf. Note that Christ triumphing over several monsters was a common theory in medieval art. Additionally, artists sometimes combined pagan and Christian imagery in the same works.
